Steemit has been called a social media site. This is true to a point but it is not the same.
Social media like Facebook is different as you have your friends and family supporting you. On Steemit you have your followers who you have gained by getting to know them and producing decent interesting posts.
The social side of Steemit is the engaging in comments and replies. Using Steem chat and discord are extra ways of communicating. Very few people have their family and friends with them in Steem.
Once mass adoption happens we will see communities spring up and maybe we will see friends and families supporting each other. There may be another Dapp like Facebook for that spring up but I have no idea what is coming.
